Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484662, here are decompositions:

149 + 31484513 = 31484662
359 + 31484303 = 31484662
569 + 31484093 = 31484662
593 + 31484069 = 31484662
683 + 31483979 = 31484662
743 + 31483919 = 31484662
773 + 31483889 = 31484662
821 + 31483841 = 31484662

Showing the first eight; more decompositions exist.
